Usually, the phenotypic ratio of F2 generation

F1 hybrid

An F1 hybrid (or filial 1 hybrid) is the first filial generation of offspring of distinctly different parental types. F1 hybrids are used in genetics, and in selective breeding, where it may appear as F1 crossbreed. The term is sometimes written with a subscript, as F1 hybrid.

is of 9:3:3:1 with more similar phenotypes to the P generation. Thereby, the F2 generation is important for the maintenance of parental traits over several generations.
